"We’re excited to add to the family,” the country singer told host Jimmy, before dishing about her three-year-old son Isaiah's feelings about becoming a big brother. "I don’t think [he knows what's happening] for real. He’ll be really sweet and talk to my belly and kiss my belly. He’s the sweetest little boy. I mean, no kid can really know that their life is going to change. He’ll just have to share mommy.”

"We did ask him [if he had a baby name idea], and he did say, ‘Isaiah Michael Fisher,’ which is, of course, his name and would be confusing,” Carrie joked. "He wants to name everything his name because he thinks that’s special.”

If that wasn't cute enough, Carrie also revealed that she sometimes listens to her son sing to see if he's got the chops to follow in her footsteps. "I try [to listen and see if he can sing], is that wrong?" she said. "I’m like judging my three-and-a-half-year-old child to see if he can sing.” She added, "If he is not musically inclined that is fine. I’m excited to find out what he loves and is passionate about and is good at, and I will support that. But I really want him to sing.”

“You might be wondering or asking, ‘Carrie, why is your tour starting in May?’ Well … yay!” she said, revealing balloons that spelled out “BABY” above her head. “Mike and Isaiah and I are absolutely over the moon and excited to be adding another little fish to our pond.”
